I recently puchased a Lincoln car with Navigation which can display pictures. I tried this with a photo copied from a PC file(both XP and Vista syss.) and I get a message saying Disc is bad or in wrong format. In the car manual it reads that the format must be ISO 9660 and that UDF is not supported. I do not find a format option of ISO 9660 on either of my PCs--just UDF are listed.How can I solve this problem?
